					Simple Backup Strategy for Home Computers
From Corey Keating (www.ComputerSecurityNW.com)
    This document contains the most essential elements of a backup strategy for your computer. If
you don't feel comfortable with these issues and want a detailed discussion of each of these topics,
please see the other document: "Detailed Backup Strategy for Home Computers".
    Backing up the information on your computer is critical! (Just ask anyone who has lost years
worth of irreplaceable photos or important documents just because they thought their hard drive
would never fail.) Your backup plan can range from something very simple to very elaborate, but you
need to have a plan to backup regularly and the confidence that you can restore your data if your
computer crashes or gets stolen. Create a plan that works for you. Don't get caught in the "it-won't-
happen-to-me" syndrome; just start backing up today!
   Although there are other methods to backing up than what is described in this document, many of
the other methods are more complicated and take more effort. (For example, if you are a technically
savvy computer user, you might be aware of the location of all the different types of data you need to
protect and may be able to manually copy your data to a flash drive or write it to CDs.) However,
most of us will not interrupt our busy schedules for a complicated or difficult process. Please work to
make your backup process as simple and as automated as possible.

In Nothing Else, Read This
    I strongly urge you to follow the directions in this document to form a backup plan with
appropriate hardware and software; you must prepare to recover your critical files (pictures, contacts,
emails, budgets, correspondence, etc.) when your computer crashes or needs to be rebuilt. However,
if you choose not to do so, then at least do the minimum and copy your files to a flash drive or burn
them to a CD; in this way you will not permanently lose all copies of any irreplaceable information.
Please remember Corey's Hypothesis of Data Loss: "If you want to lose it, keep only one copy of it."

Overview of Simple Backup Strategy
     In order to be ready for the time when you will need to rebuild your computer, (and it *will*
happen, whether out of necessity or by choice) keep all of your Program CDs and Serial Numbers
in one spot. This includes all Operating System CDs/Serial Numbers (such as Windows XP, Vista,
OS X, etc.) and all application programs you run on your computer. If you loose your serial numbers
you may have to spend a lot of money to re-purchase software you technically already own.
An overview of the steps to protect all your data includes:
1) Keep all your documents in one location on your computer (e.g. Windows "My Documents").
2) Purchase and setup backup hardware and software (or sign-up for online backup). (Details below.)
3) Configure the backup to occur regularly (automatically if possible). Decide how often you need to
   backup, based on your needs.
   3) (a) Periodically check the log files for the backup software to ensure that your automatic
   backups have completed successfully. (Worse than "not having a backup" is "thinking you have
   one when you actually don't!")
4) Before you are done with your initial program setup, test to make sure you can restore one file
   from your backup; that way you know your data was backed up successfully.
5) If you use a method to backup other than the ones recommended here, then make sure you feel
   comfortable with the "restore" process since you might not easily be able to get help from
   someone who is familiar with the backup method you have selected.

If you have a Windows PC
    Make sure you keep all your data in the "My Documents" area of your computer and backup this
folder to your external device regularly. Make sure to also backup your email address book (and
emails if they are stored locally) and your Internet Favorites (bookmarks).

Option 1 - Backup to External Hard Drive with Windows PC
1) Buy an external hard drive to connect to your computer; it should be at least twice as large as
   your internal hard drive (or a minimum of 500 Gigabytes or 1 Terabyte).
2) You will need to buy a backup program to manage the backup to the external device. Based on
   my experience, I highly recommend purchasing Acronis True Image Home; it may cost $50, but
   it will create a backup "image" of your computer (which makes restoring very easy), will
   maintain multiple copies of your data, and make it easy to backup your email.
   a) Please see the end of this document for detailed directions on how to use Acronis software.
   b) Some external hard drives come with their own backup program. If you choose to use this
       program instead of a program like Acronis, then please be aware that someone else may not
       easily be able to help advise you if you need to do a restore. Make sure you understand the
       restore process before there is an emergency.
3) Set your software to backup automatically, on a regular schedule (probably once per week or
   month, based on, "How hard would it be for me to recreate all this information if my hard drive
   crashed?" Or to replace those pictures? What if I lost all the emails from this last week?). You
   may also choose to backup critical files that change frequently to a flash drive.

Option 2 - Backup to Online Service with Windows PC
1) An alternative to backing up your data to an external hard drive is to use an "online" service.
   a) Advantages: (1) One advantage for using an online backup service is that the software is
      usually easy to configure; no need to purchase anything else, just download the software and
      away you go. (2) Another advantage is that a copy of your data is stored "offsite", at an
      external location. In case your computer is lost, stolen, or destroyed, you still have a backup
      of all your critical data.
   b) Disadvantages: (1) Be aware that backing up over an Internet connection is much slower than
      connecting to a local hard drive. Backing up lots of data (like photos, etc.) will take
      considerably longer than to a local drive. (2) These online services also cost you a monthly
      fee, as opposed to the one-time cost of your external hard drive and backup software.
2) Online Backup Options: Here are some recommendations for online backup services:
   a) SOS Online Backup (www.sosonlinebackup.com) - SOS Online Backup is a very full-feature
      online backup solution, backing up files continuously as changes occur. If you have many
      gigabytes of data to backup, it would take weeks to do so; in this case SOS provides the
      option to send your data to them on a disk and then only changes will be uploaded over the
      Internet. The SOS software can also be used to make local backups onto disk. The SOS
      servers store virtually unlimited versions of your files; you can restore files from any date you
      chose.
   b) Mozy Pro (www.mozy.com/pro) - Mozy Pro is a reliable online backup option, but may not
      be as easy to use or offer some of the advanced features as SOS Online, such as the option to
      backup locally.
   c) If you have only 2 gigabytes or less to backup, then you can use the online Mozy Home
      backup for free. (www.mozy.com/home) Alternatively, if you have information that is
      updated often, then in addition to your full backup plan, you may want to use Mozy Home to
      back up your most critical data on a daily basis. (However, do *not* choose to use the "for

            Download from: www.ComputerSecurityNW.com                  Version 2.0, September 2009, Page 2
         pay" version of Mozy *Home* to backup all your data; if you chose Mozy to backup all your
         data, use the Mozy *Pro* version.)

If you have an Apple Macintosh Computer
     If you have a Macintosh with the Leopard or Snow Leopard OS X, then buy an external hard
drive that is at least twice as large as your internal hard drive (or a minimum of 500 Gigabytes). Plug
it in and initiate the Time Machine program. Plug in the hard drive whenever you are home or plug it
in once a day if you are on the go. Your job is done; let Time Machine do its job! It will keep a
current backup of all files that change on your computer. If you ever have to restore your computer,
the Mac will ask you if you want to restore from a Time Machine backup at the time of install.
(When using Time Machine, your external hard drive needs to be dedicated to backups; don't try to
use it for copying other files to since Time Machine needs full control of that drive. There are ways to
partition a hard drive for shared use with Time Machine, but that is beyond the scope of this
document.)

   If you own an older version of OS X, like Tiger, then you will need to install a separate backup
program (instead of using OS X Time Machine) and follow the directions for backing up a Windows
PC (above). I suggest using either SilverKeeper or SuperDuper! as your backup software.

    As an option, you can also use an online backup service like Mozy Pro with your Mac. Please see
the comments made above concerning online backup services; both the advantages and disadvantages
apply to Macs too. (SOS Online Backup software does not work with Macs.)

Details for Using Acronis Backup Software with Windows
    If you choose to use Acronis software, the actual name of the backup software is "Acronis True
Image Home". One place that offers a good price for Acronis is the website: www.allacronis.com
For the backup concepts discussed for Acronis in this document, please see the video tutorials listed
below for complete instructions on how to accomplish these tasks.

1) First Create a Bootable Rescue Media CD to Prepare for a Complete Restore
If you downloaded Acronis, you will want to create a bootable rescue media CD. If your system
crashes, you will be able to boot from this CD, run the Acronis program (stored on the CD), and
choose to restore you computer from a disk image that you will create (explained below). To create
this CD, choose "Create Bootable Rescue Media" and choose to create it (burn it) to a CD. (If you
purchased Acronis on CD, that CD is already your bootable rescue CD; no need to create one.)

2) Create Your First Full Disk Image
The backup plan for most users will consist of choosing to backup "My Computer" through the
Acronis program. This will create a Disk Image of your hard disk which includes *everything* on

              Download from: www.ComputerSecurityNW.com                              Version 2.0, September 2009, Page 3
your hard disk (including your Windows operating system, your applications, and all your data files).
You should choose to store this backup on your external hard drive. Give the backup a file name that
makes sense to you (e.g. "MyComputer-August2009.tib" - the extension "tib" stands for "True Image
Backup" and is the extension that all your backup files will end with.) Choosing all other Acronis
program "default" options for back up is fine.

3) Schedule Regular Differential Backups of "My Computer"
After making a full/complete disk image of your computer, you then want to do regularly scheduled
backups to capture all changes that you make on your computer. These subsequent updates are made
by choosing to do a "Differential" backup of "My Computer" and choosing to save this Differential
backup to the *same file name* as you choose for your complete/initial backup. (e.g. "MyComputer-
August2009.tib"). All the changes made to your disk will be backed up.

4) After Some Months, Back Up Data Files Rather Than Your Entire Computer
    After 6 months or a year of creating differential backups of your "Disk Image" (as described in
step 2 above), you will want to change the process to instead back up only your data files (not your
entire computer). The fact is that after a year (or less) of running Microsoft Windows, after a
computer crash you would most likely want to reload your computer from the original Windows and
application CDs rather than restoring a "year-old disk image" and the latest "differential backup".
This is because Windows does regular updates to system files, updates have been applied to various
application programs, you may have installed and un-installed software (which can leave stray files
on your computer), etc.; all these processes tend to leave Windows more unstable than when freshly
installed.

    For those same reasons, you might also choose this option if it has been a couple years since your
computer was rebuilt at the time you start your backup regimen. Furthermore, if your external hard
drive is not large enough to store multiple images of your internal disk drive, then you again may
choose just to backup your data files rather than the entire disk drive.

    Another reason for doing a file/data backup of your computer is that after two or three years you
will most likely purchase a new computer. You would use the file restore to transfer your data to the
new computer as opposed to doing a restore from a disk image from the older computer.

(a) If you choose to not make a disk image, but to backup your data files, the only change you would
   make to the instructions above (in step #2) would be to choose to backup "My Data" in Acronis
   (rather than "My Computer"). Again, make sure to store this backup on your external hard drive.
   (Remember, in order for this method to work effectively it is critical to store all data files in the
   "My Documents" folder on your computer.)
(b) You will also want to run this backup again and choose to backup "My Email" if you use MS
   Outlook for your email; the "My Data" option will not backup your Outlook email and contacts.
(c) The first time you do a backup you will want to do a "Complete" backup of your data files.
(d) Subsequently you would choose to do a "differential" backup of your data files (and email).


Comments about Restoring with Acronis on Windows PC
   If you need to do a "restore" of your computer from your backup, here are some things to
consider. Before you enter a crisis, you should watch the tutorials on restoring listed below (Videos 7
and 9).

            Download from: www.ComputerSecurityNW.com                    Version 2.0, September 2009, Page 4
    Disk Image Restore: Use this option if you backup a disk image of your computer ("My
Computer" in Acronis). If your computer crashes and you want to do a restore your disk image, then
you would first restore your original complete disk image and then restore the latest differential
backup of your computer. Restoring the initial image will put your computer back to the original state
(including your operating system, programs, and old data files) and restoring the differential backup
will reinstate all changes made since the time the initial image was created.
    Data File Restore: Use this option if you backup your data files and email ("My Data" and "My
Email" in Acronis) rather than doing a Disk Image ("My Computer" in Acronis). If you need to
reload your computer, then you would install your Windows operating system and all application
programs from the original CDs. In order to get your data from your backup, you would then restore
your original "full backup" of your data files and then restore the latest "differential" backup of your
data files. (You need to repeat this process for restoring email.)
    Starting with Disk Image then Adding Data File Restore: If you started your backup regimen
with a backup of your entire computer to create a Disk Image ("My Computer" in Acronis), but after
some time switched to backing up only your data files ("My Data" and "My Email" in Acronis), then
you have two options for reloading your computer, as follows:
(1) You can reload your computer from CDs and then restore your data files (as described in "Data
File Restore" above) or (2) you can choose to restore the original Acronis "Disk Image" (as described
in "Disk Image Restore" above) and then restore your most recent data file backup (both the
"original" data file and the latest "differential"), overwriting the old data from the original image.


Tutorials for Using Acronis Backup Software with Windows
If you want more detailed information about using Acronis, there are some tutorials available at this
web site: www.acronis.com/homecomputing/products/trueimage/video10/
(Although these tutorial videos are for the previous version of Acronis True Image Home, the
concepts are the same and menus are very similar.)
(If the first link on each tutorial page [Streaming Version for Watching Online] does not work, then
choose the second option [Download Version (WMV)] and watch it with Windows Media Player.) (If
you hear mention of the "Acronis Disk Director", it is a different product that you do not need.)
